The EBP previews methodologies and processes in order to identify evidence of whether a certain treatment or diagnosis is effective, strategies to evaluate the estrateyia of studies and mechanisms to implement it in care. The results obtained through such reviews pocot biased, do not exhaust all the literature available about the theme and are usually inconclusive. This abstract may be abridged. Once the research question is formulated, the following stage is the beginning of the bibliographic search for pucot, which allows for the recovery of evidence in the databases, and can be schematized in the following stagesElements of a systematic review.

For this reason, it is essential that every researcher is familiarized with strategies to develop a research question, as each one of its components must be defined. Semin Perinatol February; 21 1: Int J Nurs Pract December;7 6: In this review a description of the characteristics of a good research question and its construction by the strategy known as PICOT will be made.
